Check Digit Verification of cas no
The CAS Registry Mumber 203519-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,5,1 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203519-80:
(8*2)+(7*0)+(6*3)+(5*5)+(4*1)+(3*9)+(2*8)+(1*0)=106
106 % 10 = 6
So 203519-80-6 is a valid CAS Registry Number.

Novel 3-Substituted 3-Acylaminobenzo[b]furan-2(3H)-ones: Synthesis and Chemiluminescence Studies
Matuszczak, Barbara
, p. 20 - 25 (1998)
Starting from 3-acylaminobenzo[b]furan-2(3H)-ones (2) 3-arylthio substituted derivatives (3) were prepared via novel N-acylimines (5). Compounds of type 3 and 5 were found to show visible chemiluminescence upon base-induced oxidation in the presence of an
